    摘要: A process for catalytically cracking a hydrocarbon oil containing sulfur and/or nitrogen hydrocarbon constituents by dissolving excess hydrogen in the liquid hydrocarbon feedstock in a mixing zone at a temperature of 420° C. to 500° C. and a hydrogen-to-feedstock oil volumetric ratio of 300:1 to 3000:1, flashing the mixture to remove remaining hydrogen and any light components in the feed, introducing the hydrogen saturated hydrocarbon feed into an FCC reactor for contact with a catalyst suspension in a riser or downflow reactor to produce lower boiling hydrocarbon components which can be more efficiently and economically separated into lower molecular weight hydrocarbon products, hydrogen sulfide and ammonia gas and unreacted hydrogen in a separation zone. Hydrogen present in the liquid phase enhances the desulfurization and denitrification reactions which occur during the conversion process and allows for the removal of significantly more sulfur- and/or nitrogen-containing contaminants from the feedstock in an economical fashion.

    摘要: An integrated process and system for conversion of a heavy crude oil to produce transportation fuels is provided. The process includes separating the hydrocarbon feed into an aromatic-lean fraction and an aromatic-rich fraction. The aromatic-rich fraction is hydrocracked under relatively high pressure to convert at least a portion of refractory aromatic organosulfur and organonitrogen compounds and to produce a hydrocracked product stream. Unconverted bottoms effluent is recycled to the aromatic separation step. The aromatic-lean fraction is cracked in a fluidized catalytic cracking reaction zone to produce a cracked product stream, a light cycle oil stream and a heavy cycle oil stream. In certain embodiments the aromatic-lean fraction can be hydrotreated prior to fluidized catalytic cracking.

    摘要: A delayed coking process includes: a. introducing a fresh hydrocarbon feedstock containing undesirable sulfur and/or nitrogen compounds for preheating into the lower portion of a coking unit product fractionator; b. introducing at least a portion of an intermediate fraction derived from the fractionator and at least one adsorbent material that selectively adsorbs sulfur- and/or nitrogen-containing compounds into a mixing zone to form an adsorbent slurry stream; c. discharging a bottoms fraction from the fractionator; d. adding all or a portion of the slurry stream to the bottoms fraction to form a mixed coking unit feedstream; e. heating the mixed feedstream in the coking unit furnace to a predetermined coking temperature; and f. passing the heated mixed feedstream to a drum of the delayed coking to produce a delayed coking product stream while depositing the adsorbent material having adsorbed sulfur and/or nitrogen compounds with the coke in the coking drum.

    摘要: Initial high sulfur levels of a hydrocarbon feedstock are reduced to desired low levels without the need for integration of substantial new equipment or hardware with existing hydroprocessing reactors. Ionic liquids are utilized as organic sulfur extraction agents and are added to and mixed with the hydrocarbon feedstock containing organosulfur compounds downstream of an existing cold separator vessel. The ionic liquid and hydrocarbon mixture is maintained in a contact vessel under conditions which promote the formation of ionic sulfur-containing derivatives that are soluble in the ionic liquid to be formed, thereby enabling extractive removal and separation of the organosulfur compounds from the feedstock.

    摘要: A system and process for desulfurizing a hydrocarbon feed stream containing organosulfur compounds is provided. In general, the system includes a conventional hydrotreating unit through the high pressure cold or hot separator. Aqueous oxidant and an oxidative catalyst are mixed with the hydrotreated hydrocarbon effluent from the high pressure cold or hot separator, and oxidative desulfurization reactions occur in the low pressure separation zone, thereby minimizing or eliminating the requirement of additional oxidative desulfurization reactors.
